Introduction
Use this guide to troubleshoot common issues where a live stream is not recording correctly or audio is missing, incorrect, or not initialized as expected. The steps below apply to live streaming workflows that use recording during stream startup and RTMP publication, as well as encoder-based audio configuration.
Issue description
This issue can occur when the recording destination is not configured, the recording option is not enabled at startup, RTMP recording is not set separately, or the encoder is using the wrong audio channel selection. In some cases, the encoder may also need to be restarted to clear a configuration mismatch.
Signs
- The live stream starts, but no recording file is created.
- Recording starts, but the output file is empty or incomplete.
- Audio is missing from the stream or recording.
- The wrong audio channels are present in the output.
- The encoder appears to start normally, but audio initialization fails in the logs.
Basic troubleshooting steps
- Confirm that a recording destination is configured.
- If recording should start automatically, make sure the recording checkbox is enabled during stream startup.
- If you are publishing via RTMP, verify that recording is configured separately from the publication settings.
- Check that the correct audio channels are selected in the encoder settings.
- Restart the encoder to clear any temporary configuration mismatch.
Diagnostic tools and resources
- Encoder configuration panel
- Stream startup settings
- Application or system logs
- Recording destination path or storage location
Advanced troubleshooting steps
Step 1: Verify recording configuration
Check whether the stream has a recording destination set. If your workflow requires manual activation, confirm that the recording checkbox is enabled before or during stream startup. For RTMP publication workflows, make sure recording is enabled in the dedicated recording configuration, not only in the RTMP output settings.
Step 2: Review encoder audio settings
Open the encoder settings and confirm that the correct input and output audio channels are selected. If the stream contains multiple channels, verify that the intended channel mapping is active and that no silent or unused channel has been selected by mistake.
Step 3: Restart the encoder
If the configuration looks correct but audio is still missing or incorrect, restart the encoder. This can resolve temporary mismatches between the active stream configuration and the encoder state.
Step 4: Check logs for errors
Review the logs for messages related to audio initialization or recording threads. These entries can help identify whether the issue is caused by a channel selection problem, a recording setup error, or a failure to start the recording process.
Contact support
If the issue continues after completing the steps above, contact Cires21 support and include the following information: stream type, recording configuration, encoder settings, relevant log excerpts, and a description of the audio problem.
Additional information
For faster resolution, note when the issue started, whether it affects all streams or only specific channels, and whether the problem occurs on first startup or after a configuration change. This information can help isolate whether the root cause is related to recording setup, audio mapping, or encoder state.
Conclusion
Most recording and audio issues can be resolved by confirming the recording destination, enabling the recording option at startup, checking RTMP recording settings separately, and verifying encoder audio channel selection. If needed, use logs to identify initialization or thread errors and escalate to support with the relevant details.
